Step-by-step explanation:
7/3+3(2/3−1/3)^2
=7/3+6/9-3^2/9
=7/3+6/9-9/9
=7/3+2/3-3/3
=6/3
=2
Answer
V=19
You put a +11 under the -11 then you can move the +11 to the other side of the equal sign. Then u add them which equals 19.
Ratio in the first sample = 250/1000 = 1/4 = 0.25
ratio in the second sample = 750/2000 = 0.375
hence ,<span> there is a greater proportion of smokers in the second city than in the first.

Answer:
339.336 m^2
Step-by-step explanation:
Given data
Radius= 6meters
We know that the surface area of a half-sphere is given as
A=3πr^2
A= 3*3.142*6^2
A= 3*3.142*36
A=339.336 m^2
